The present invention consists of a garbage incinerator constructed to cremate the garbage in an expeditious manner by selectively charging or'feeding the wet and dry garbage into different parts ofthe incinerator.

Another object ofthe invention is to provide-an incinerator which is equipped with a=water jacketed-chute which prevents warping or distortion of "the chute'due to the in- 110 tense heat in the incinerator into which the i 2 rationtof'thegrateby the heat from the ashes.

A still further :object of the invention" is to provide grates which :are arranged in superposed relation in the eincinera'tor housa ing to 'which the garbage is fednthrough a J convertible chute,itheilatter' being capable of rapid-adjustment topermit depositing gar- I-ba'ge onieither one ofrthe grates at theoption ofthe user. f' Y Other objects of the invention will be apzparent'from'thelfollowing description of the .present preferred "form of r the invention,

Figure 5s a detail enlarged fragmentary secgional view ofthe water jacketed chute; an, v v v V Figure-6 .is-a detail fragmentary vertical sectional viewof the water tank-usedinthe present invention. 7 v t The device of the present invention embodies a housing, generally designated 7, whichzis made of concrete or any other-suitable fire-proof material and isequipped with acharging or feeding floor 8. :Onewall of the housing .is provided with-,an'opening .9 which opens to thechargingfioor and through which garbage is adapted to be passed into the incinerator in a manner hereinafter-explained. The opening is normally closed through the medium, ofa counterbalanced door10,m0unted on the inside of the housing wall as illustrated to advantage in Figure 13. Although a single opening :9 is shown, itisof course to be: understood that a series of topen 'ings-may be5providedif desired, corresponding to the -=number Y of incinerators whichare tobeused g q p The incinerator per "se consists of a acasing or housing 11 which is preferablyymade of concrete or other plastic fire-proof material 39 and may be of anydesired-size and configuraition. The casing is provided in the sideadjacent-the housing 7 with anopening, the wall ofwhich is covered by a metal frame 12;, A portion'of. the incineratorcasing opening is in alignment with the opening .9 of the housing 7, whilethe remainderofthe opening extends appreciably below theopening 9 and is adapted' for the reception of oneend of achutej 13. "The chute 13 has its upper end impinged r against the outside wall of the housing '7 below the opening 9 and tapers inwardly toward its opposite end," the latter projecting through the casing 11 of the incinerator. The c'hute is-provided with a hollow "bottom and hollow sides 14, 'in 1 order ;to provide a :water space,ftherebyprovidinga water jacket -for' -the entire chute. The water jacket ;in;the bottom of the chute is'provided with 'a-series of :=bafiles ,15, which are preferably :arranged casing 11 is reduced from a point near the bottom of the casing upwardly toward the top of the latter, the juncture of the reduced part of the casing with the bottom of the latter providing a base which receives the marginal edge of an ash deflector 16 hereinafter de 7 scribed, upon which is superimposed a fire wall 17. mounted in the casing 11 and is preferably made of fire brick in order to withstand the intense heat generated by the burning of the garbage. Furthermore, the fire wall is spaced from the casing to provide an air passage-way 18 for an obvious purpose. The upper end of the fire wall is reduced to provide an annular shoulder which supports a truncated cone shaped draft collar 19, which latter is also preferably made of fire brick and prevents downdraft through the incinerator, in addition to preventing gases from escaping from the incinerator until they are completely consumed.

Mounted in the fire Wall 17 near the bottom ofthe latter and directly above the ash deflector 16 is a grate 20 of standard construction which is adapted for the reception of dry garbage and is arranged in the path of the chute 13, so that garbage deposited on the latter will gravitate directly on to the grate. A wet grate 21 is superposed above the grate 20 and is adapted for the reception of wet garbage The grate 21 is preferably composed of-a series of tubes, the terminals of which communicate with conduits 22, one of which is arranged-in proximity to the chute 13 and has a pipe 23 leading therefrom which communicates with the water jacket in the bottom of the chute 13 at the lower end of the latter, in a manner illustrated to advantage in Figures 2 and 4 of the drawings. The other conduit 22 is in communication with an intake pipe 24, the latter extending downwardly from the bottom of a water tank 25. V Consequently,'water passing from the tank 25 flows through the pipe .24: into the grate 21 and thence through the pipe 23 into the chute 13. The upperend of the chute 13 is in communication with a manifold 26 which in turn communicates with a return pipe 27 which latter leads to the upperend of the water tank 25.

It is therefore apparent that the water, after having passed through the grate 21 and chute '13 isreturned to the tank 25 for recirculation through the grate and the chute. In this 'way there is a constant circulation of water thpough the grate and chute. Not only does this circulation of water tend to effect drying of the garbage, but in addition warping, dis- The fire wall is concentrically side of its apex with an opening 28 which is directly above an endless conveyor belt 29 so that ashes gravitating from the deflector will be deposited directly on the belt and carried by the latter outside of the incinerator casing. It is of course to be understood that the conveyor belt may be operated in any desired manner and may be of any desired construction in order to effectively transport the ashes. r The water tank 25 is provided with a s'up ply pipe 30 which is equipped with a float operated-valve-in order to automatically close communication through the supply pipe when the water has reached a predetermined level in the tank. Moreover,the'tank is provided with an overflow pipe 31 in order to takecare of excess water accumulating'in the tank due to failure of the valve 'to operate or for any other reason. Pivotally mounted in the frame 12'of the incinerator opening is a plate 32 which may be made of metaland is of sufficient length to extendfrom the interior ofthe fire wall of the incinerator tothe charging floor 8 of the housing 7. This plate serves as a slide or chute over which the Wet garbage ispassed for engagement with the water grate '21. It will be noted that when the plate 32 is-in' an operating position, as shown in Figure2 of the drawings, the inner end thereof ispositioned above the water grate to direct the garbage on to thelatter. When in this ositionthe plate 32 preventsthe garbage rom impingingfagainst the chute .13 and correspondingly. prevents depositing of the garbage on'the grate 20; However, the plate 32 can be swung into the frame'12, thereby cutting ofi communication betweenthe charging floor 8 andthe water grate 21 and establishing communication between the charging floor and grate 20 by reason of the stationary chute 13.v

In use of this device the wet garbage is deposited in'the incinerator by passing the same through the opening of the housing 9 onto the plate 32. The garbage thus suspended on the water grate is permitted to dry out and as it is consumed the cremated residue'gravitates downwardly into engagement with the grate 20 where complete cremation is effected'and the ashes permitted to gravitate into the deflector 16. Where dry garbage is to be incinerated, the garbage passes directly from the charging floor 8 on to the chute 13 and from there on to the grate 20, where it is directly burned. In view of the fact thattheinner end of'the chute 13 of necessity is located in close proximity to the grate 20, it has been found that in the absence of suitable means to cool the chute the latter is soon Warped by the intense heat and thereby rendered unsuitable for use. By Water jacketing the chute however, warping is prevented and elfective functioning of the chute insured at all times.

It is of course to be understood that numerous changes may be made in this device, especially in the details of construction, proportion and arrangement of parts Within the scope of the claim hereto appended. I am aware that the incinerator may be used independently of the housing such as designated 7 herein, and the garbage deposited directly 7 on the chute. Where, however, the incinerator is arranged in proximity to a housing, i into whlch the garbage is transported, 1t is
